Background. Acute generalized peritonitis in resource-poor countries is still a health challenge due to late diagnosis, surgical delay, and specialists’ unavailability. These are the foremost determinants of surgical morbidity and mortality. We report the experience of a peripheral hospital in Benin not equipped with specialized surgeons. Methods. This is an observational, retrospective, and descriptive study including patients operated for acute generalized peritonitis at the Atacora Departmental Hospital Centre, Benin, where unfortunately CT scan and intensive care unit are still not available. Most of surgical activities were performed by a general practitioner with previous surgical training (but no surgical specialization). Age, gender, cause of peritonitis, surgical procedures, and postoperative outcome were evaluated. Results. Sixty-three patients were included. The mean age was 23.2 years and sex ratio M/F 1.5. The mean surgical delay was 26 hours (range: 6–92 hours). An ileal typhoid perforation was found in 40 patients (63.5%), and 35 of them (87.5%) underwent a primary perforation repair without bowel resection. 73% of surgical procedures were performed by the general practitioner. Morbidity was 34.9% and mortality was 14.3%. The average postoperative hospital stay was 12 days (range: 11–82 days). These results were comparable to those observed in the subgroup of patients (17 cases) operated by the general surgeons (morbidity 32.6%, mortality 13.0%, and average postoperative hospital stay 11 days, range: 1–58 days). Conclusion. Acute generalized peritonitis requires urgent management, and it can be effectively carried out, in a context of limited resources, by a general practitioner with surgical skills.

Abstract Background: Acute generalized peritonitis is a highly lethal and unfortunately common disease in developing countries. Moreover, lack of specialists and their concentration in main towns, expose the patients to a high but avoidable risk of complications or death. We report the experience of a peripheral hospital in Benin not equipped with specialized surgeons.Methods: This is a descriptive study including patients operated for acute generalized peritonitis from March 1st 2018 to November 30th 2019 at the Atacora Departmental Hospital Centre, Benin. This hospital lacks a CT scan and an intensive care unit. Most of the surgical activity is performed by a General Practitioner with previous surgical training (but no surgical specialization). For the purpose of the study, we evaluated the following patients’ data: age, gender, cause of peritonitis, surgical procedures, postoperative outcome and hospital stay. Results: A total of 63 patients were selected, with a mean age of 23.2 yrs and a sex ratio of 1.5. The mean operative delay was 26 hours (range 6 - 92 hours). An ileal “typhic” perforation was found in 40 patients (63.5%) and 35 of them (87.5%) could benefit of primary repair without bowel resection. 73% of surgical procedures were performed by the general practitioner. Morbidity was 34.9%, mainly represented by surgical site infections. The overall mortality was 14.3%. The average postoperative hospital stay was 12 days (range 11 - 82 days). Patients operated by the General Practitioner were in line with the overall results (morbidity 32.6%, mortality 13.0% and average postoperative hospital stay 11 days, range 1 - 58 days). Conclusion: Acute generalized peritonitis requires urgent management and can be effectively carried out, in a limited resources context, by a general practitioner with surgical skills. The respect of hygiene rules, the availability of qualified human and structural resources as well as the effectiveness of the care costs coverage by the Government are essential to reduce the peritonitis burden in Benin.

Abstract Background Laparoscopic anatomic hepatectomy (LAH) has gradually become a routine surgical procedure. However, how to expose the whole hepatic vein and avoid the hepatic vein laceration is still a challenge because of the caudate lobe, particularly in right hepatectomy. We adopted a dorsal approach combined with Glissionian appraoch to perform laparoscopic right anatomic hepatectomy (LRAH). Methods Twenty patients who underwent LRAH from January 2017 to November 2018 were retrospectively analysed. Of these patients, seven patients underwent laparoscopic right hemihepatectomy (LRH group), seven patients who underwent laparoscopic right posterior hepatectomy (LRPH group), and six patients who underwent laparoscopic hepatectomy for segment 7 (LS7 group). The paracaval portion of caudate lobe could be transected firstly through dorsal approach and the corresponding major hepatic vein could be exposed from its root to the peripheral branches safely. Due to exposure along the major hepatic vein trunk, the remaining liver parenchyma could be quickly transected from dorsal to cranial side. Results The mean age of the patients was 53.8 years and the male: female ratio was 8:12. The median operation time was 306.0 ± 58.2 min and the mean estimated volume of blood loss was 412.5 ± 255.4 mL. The mean duration of postoperative hospital stay was 10.2 days. The mean Pringle maneuver time was 64.8 ± 27.7 min. Five patients received transfusion of 2–4 U of red blood cells. Two patients suffered from transient hepatic dysfunction and one suffered from pleural effusion. None of the patients underwent conversion to an open procedure. The operative duration, volume of the blood loss, Pringle maneuver time, and postoperative hospital stay duration did not differ significantly among the LRH, LRPH, and LS7 groups (P > 0.05). Conclusions Dorsal approach combined with Glissonian approach for right lobe is feasible and effective in laparoscopic right anatomic liver resections.

Introduction: Gallstones are common biliary pathology. The Vast majority of subjects are asymptomatic. About 0.2% of the population suffering from gallstones develop acute cholecystitis every year. In case of acute calculous cholecystitis, cholecystectomy can be performed early i.e during the same admission or interval i.e after 6 weeks of conservative management. Objective: To compare the early and interval cholecystectomy in acute calculous cholecystitis for morbidity, postoperative hospital stay, total hospital stay and complications. Study Design: Quasi-experimental study. Setting: Department of Surgery Bahawal Victoria Hospital Bahawalpur. Duration of Study: Two year study from December 2007 to December 2009. Subject and Methods: Sixty patients fulfilling the inclusion criteria were selected for this study. The patients were divided into two groups. Group A patients were managed by early cholecystectomy and group B patients by intervalcholecystectomy. Postoperatively patients were evaluated for postoperative hospital stay, total hospital stay and postoperative complications. Results: The mean age of the patients in group A was 42.2 + 10.7 years and in group B was 42.2+ 10.7 years. The Male to female ratio was 1:4 in both groups. The mean postoperative hospital stay in group A was 4.0+ 1.8days and in group B was 3.8+ 1.4 days. The mean total hospital stayin group A was 6.5 + 1.7 days and in group B was 10.2 + 1.3 days. The P value was less than 0.001, which was significant. In distribution of postoperative complications, in group A there were 1(3.3%) injury to biliary tree, 4(13.3%) wound infection,1(3.3%) wound haematoma, 3 (10%) seroma and 1(3.3%) wound dehiscence. While in group B there were 1(3.3%) injury to biliary tree, 3(10%) wound infection,2 (6.7%) wound haematoma, 2(6.7%) & no patient of wound dehiscence. Conclusion: Our study suggests that early cholecystectomy is a better treatment option than interval cholecystectomy because it has less total hospital stay, needs single hospital visit and has no risk of developing complications during wait for surgery.

Purpose: Various surgical strategies including combined approach and spinal osteotomies in severe rigid scoliosis had been reported with significant perioperative complication rates. The use of single-staged posterior spinal fusion (PSF) utilizing a dual attending surgeon strategy for severe rigid scoliosis has not been widely reported. Methods: This was a retrospective study aimed to evaluate the perioperative outcome of single-staged PSF in severe rigid idiopathic scoliosis patients (Cobb angle ≥90° and ≤30% flexibility). Forty-one patients with severe rigid idiopathic scoliosis who underwent single-staged PSF were included. The perioperative outcome parameters were operation duration, intraoperative blood loss, intraoperative hemodynamic parameters, preoperative and postoperative hemoglobin, transfusion rate, patient-controlled anesthesia morphine usage, length of postoperative hospital stay, and perioperative complications. Radiological parameters included preoperative and postoperative Cobb angle, correction rate, side-bending flexibility, and side-bending correction index. Results: The mean age was 16.9 ± 5.6 years. The mean preoperative Cobb angle was 110.8 ± 12.1° with mean flexibility of 23.1 ± 6.3%. The mean operation duration was 215.5 ± 45.2 min with mean blood loss of 1752.6 ± 830.5 mL. The allogeneic blood transfusion rate was 24.4%. The mean postoperative hospital stay was 76.9 ± 26.7 h. The mean postoperative Cobb angle and correction rate were 54.4 ± 12.8° and 50.9 ± 10.1%, respectively. The readmission rate in this cohort was 2.4%. Four perioperative complications were documented (9.8%), one somatosensory evoke potential signal loss, one superficial infection, one lung collapse, and one superior mesenteric artery syndrome. Conclusions: Severe rigid idiopathic scoliosis treated with single-staged PSF utilizing a dual attending surgeon strategy demonstrated an average correction rate of 50.9%, operation duration of 215.5 min, and postoperative hospital stay of 76.9 h with a 9.8% perioperative complication rate.

OBJECTIVEThe object of this study was to compare the safety and accuracy of pedicle screw placement using the TiRobot system versus conventional fluoroscopy in thoracolumbar spinal surgery.METHODSPatients with degenerative or traumatic thoracolumbar spinal disorders requiring spinal instrumentation were randomly assigned to either the TiRobot-assisted group (RG) or the freehand fluoroscopy-assisted group (FG) at a 1:1 ratio. The primary outcome measure was the accuracy of screw placement according to the Gertzbein-Robbins scale; grades A and B (pedicle breach < 2 mm) were considered clinically acceptable. In the RG, discrepancies between the planned and actual screw placements were measured by merging postoperative CT images with the trajectory planning images. Secondary outcome parameters included proximal facet joint violation, duration of surgery, intraoperative blood loss, conversion to freehand approach in the RG, postoperative hospital stay, and radiation exposure.RESULTSA total of 1116 pedicle screws were implanted in 234 patients (119 in the FG, and 115 in the RG). In the RG, 95.3% of the screws were perfectly positioned (grade A); the remaining screws were graded B (3.4%), C (0.9%), and D (0.4%). In the FG, 86.1% screws were perfectly positioned (grade A); the remaining screws were graded B (7.4%), C (4.6%), D (1.4%), and E (0.5%). The proportion of clinically acceptable screws was significantly greater in the RG than in the FG (p < 0.01). In the RG, the mean deviation was 1.5 ± 0.8 mm for each screw. The most common direction of screw deviation was lateral in the RG and medial in the FG. Two misplaced screws in the FG required revision surgery, whereas no revision was required in the RG. None of the screws in the RG violated the proximal facet joint, whereas 12 screws (2.1%) in the FG violated the proximal facet joint (p < 0.01). The RG had significantly less blood loss (186.0 ± 255.3 ml) than the FG (217.0 ± 174.3 ml; p < 0.05). There were no significant differences between the two groups in terms of surgical time and postoperative hospital stay. The mean cumulative radiation time was 81.5 ± 38.6 seconds in the RG and 71.5 ± 44.2 seconds in the FG (p = 0.07). Surgeon radiation exposure was significantly less in the RG (21.7 ± 11.5 μSv) than in the FG (70.5 ± 42.0 μSv; p < 0.01).CONCLUSIONSTiRobot-guided pedicle screw placement is safe and useful in thoracolumbar spinal surgery.Clinical trial registration no.: NCT02890043 (clinicaltrials.gov)

Introduction: Miniaturization of endoscopic instruments has gained wide popularity in the treatment of renal calculi. Retrograde intra-renal surgery and holmium laser in combination has already proven its superiority when compared to other modalities in the treatment of renal calculi. This study was conducted to assess the outcome of retrograde intra-renal surgery in renal stone disease.Materials and Methods: This retrospective study analyzed the outcome of retrograde intra-renal surgery in renal stone less than 2 cm size in the adults above 18 years of age from September 2018 to August 2019 at Patan Hospital, Nepal. The outcome was assessed descriptively on postoperative pain and fever, stone localization, stone size, stone clearance, urosepsis, operative time, hospital stay, mortality, need of the second procedure.Results: A total of 62 patients underwent retrograde intrarenal surgery, out of which 48 cases were included. The mean age of the study population was 32.4± 14 years (19-68 years). Similarly, the mean operative time was 68± 12 (48-124 minutes) and mean hospital-stay was 3.2± 1.1 days. Postoperative pain and fever were observed in 14 (29.16%) & 4(8.33%) patients respectively. Hematuria occurred in 6(12.50%) and urosepsis in 2(4.16%) of the patients. Complete stone clearance was achieved in 34(70.83%) and residual stones were present in 8(16.66%) and clinically insignificant radiological fragments were present in 6(12.50%) patients.Conclusions: Retrograde intrarenal surgery is a technically safe and effective procedure for the treatment of renal calculi, with minimal post-surgical morbidity.

Background Intraoperative hypovolemia is common and is a potential cause of organ dysfunction, increased postoperative morbidity, length of hospital stay, and death. The objective of this prospective, randomized study was to assess the effect of goal-directed intraoperative fluid administration on length of postoperative hospital stay. Methods One hundred patients who were to undergo major elective surgery with an anticipated blood loss greater than 500 ml were randomly assigned to a control group (n = 50) that received standard intraoperative care or to a protocol group (n = 50) that, in addition, received intraoperative plasma volume expansion guided by the esophageal Doppler monitor to maintain maximal stroke volume. Length of postoperative hospital stay and postoperative surgical morbidity were assessed. Results Groups were similar with respect to demographics, surgical procedures, and baseline hemodynamic variables. The protocol group had a significantly higher stroke volume and cardiac output at the end of surgery compared with the control group. Patients in the protocol group had a shorter duration of hospital stay compared with the control group: 5 +/- 3 versus 7 +/- 3 days (mean +/- SD), with a median of 6 versus 7 days, respectively ( = 0.03). These patients also tolerated oral intake of solid food earlier than the control group: 3 +/- 0.5 versus 4.7 +/- 0.5 days (mean +/- SD), with a median of 3 versus 5 days, respectively ( = 0.01). Conclusions Goal-directed intraoperative fluid administration results in earlier return to bowel function, lower incidence of postoperative nausea and vomiting, and decrease in length of postoperative hospital stay.

Video Assisted Thoracoscopic Surgery

In the treatment of primary spontaneous pneumothorax (PSP) the latest guidelines recommend video-assisted thoracoscopy, but do not specify the best technique for performing pleurodesis. Indeed, there are no clinical trials comparing the effectiveness of talc pleurodesis, mechanical pleurodesis and pleurectomy. Our objective was to compare outcomes in patients who underwent surgery for primary pneumothorax with the talc procedure or with pleural abrasion using dry gauze. Patients undergoing video-assisted thoracoscopic surgery for PSP in two hospitals were retrospectively recruited between 2007 and 2008, and followed-up until December 2010. The variables measured to compare the outcomes were: recurrence, complications, and mortality, as well as the duration of air leaks and of drainage and the length of postoperative hospital stay (in days). Statistical analysis: The two groups were compared using the Chi square test for qualitative variables and nonparametric tests for continuous variables. A total of 106 interventions were carried out in 104 patients (74 in group A: pleural abrasion with dry gauze; 32 in group B: chemical pleurodesis with talc), with a mean age of 28 years (median 25) and 85.6% were male. Complications were observed in nine patients (8.5%) and there were no deaths in the 30 days after surgery; there were, however, four cases of recurrence (3.8%). The mean air leak duration was 0.78 days (median 0), the mean drainage duration 1.95 days (median 1) and the mean length of postoperative hospital stay 2.68 days (median 2). In 74 cases (69.8%), mechanical pleurodesis was performed, while 32 cases were treated with talc (30.2%). Comparing the two groups, we did not find statistically significant differences in recurrence (4.1% vs 3.1%, P=0.82), complications (6.8% vs 12.5%, P=0.45) or mortality (no cases of death). On the other hand, the mean postoperative hospital stay was lower in the mechanical pleurodesis group than in the talc group (2.2 vs 3.8 days, P=0.005). Video-assisted surgery in the treatment of PSP is a safe technique. In the mechanical pleurodesis group, we observed the same rate of recurrence, half the number of complications and a shorter hospital stay. We consider it necessary that well-designed multicentre clinical trials be carried out to compare these techniques and determine which produces the best outcomes, providing stronger scientific evidence given that the data available to date are not conclusive.

Abstract Background The purpose of this study was to investigate the efficacy of gelatin sponge impregnated with ropivacaine on postoperative pain after transforaminal lumbar interbody fusion (TLIF) in patients with lumbar degenerative diseases. Methods We retrospectively reviewed patients who underwent TLIF in our department between August 2018 and January 2020. Patients were divided to ropivacaine group and saline group. A ropivacaine group whom received gelatin sponge impregnated with ropivacaine during operation, and a saline group whom were intraoperatively administered by gelatin sponge impregnated with saline. The two groups were compared in reference to postoperative hospital stay, postoperative complications and visual analog scale (VAS) scores. The consumption of postoperative diclofenac sodium suppository use was also recorded. The Oswestry Disability Index (ODI) scores and Japanese Orthopedic Association (JOA) scores were used for functional evaluation at 1 year postoperatively. Result A total of 127 patients were evaluated in this retrospective study. The mean postoperative hospital stay in the ropivacaine group was significantly lower than saline group. The VAS score was significantly lower in patients receiving gelatin sponge impregnated with ropivacaine as compared with patients in saline group on postoperative day 1, 2, 3 and 4. The number of patients who need the administration of diclofenac sodium suppository and the mean consumption of postoperative diclofenac sodium suppository was significantly lower in the ropivacaine group as compared with saline group. Conclusion The application of gelatin sponge impregnated with ropivacaine around the nerve root in patients undergoing TLIF can effectively control the postoperative pain and reduce postoperative hospital stay.

Abstract Purpose To compare the safety and efficacy of retrograde intrarenal surgery (RIRS) and modified Ultra-mini percutaneous nephrolithotomy (UMP) in semi-supine combined lithotomy position for the management of 1.5-3.5 cm lower pole renal stones (LPSs). Methods A total of 63 patients with 1.5-3.5 cm LPSs who underwent RIRS (n= 33) or modified UMP (n= 30) in diameter between January 2017 and January 2019 were analyzed retrospectively. Modified UMP was performed in semi-supine combined lithotomy position and a 9.5/11.5 F ureteral access sheath (UAS) was inserted during the procedure in order to maintain low pelvic pressure and to facilitate the removal of stone fragments. Base-line parameters, stone characteristics, illness condition, operation time, postoperative hemoglobin (Hb) drop, postoperative creatinine (Cr) elevation, length of hospital stay, length of postoperative hospital stay, stone-free rate (SFR) and complications were compared between the two groups. Results There were no significant differences between the two groups in base-line parameters, stone characteristics and illness condition. The mean operating time of RIRS group was longer than UMP group (95.61 ± 21.9 vs. 55.0 ± 16.1 min, p< 0.001). The mean postoperative Hb drop was less in RIRS group (7.42 ± 4.7 vs. 15.70 ± 9.8 g/L, p< 0.001). The length of hospital stay and postoperative hospital stay for RIRS were shorter than UMP (4.76 ± 1.1 vs. 5.83 ± 0.8 d, p< 0.001, 2.97 ± 0.9 vs. 4.07 ± 0.9 d, p< 0.001). The Early SFR was higher in UMP group (54.5 vs. 80.0%, p< 0.050) while SFR at 1-month and 3-months postoperatively was similar in both groups (p= 0.504, p= 0.675). There were no significant differences between the two groups in complications (p= 0.228). Conclusion For patients with 1.5-3.5 cm LPSs, both modified UMP and RIRS are safe and viable. The modified UMP technique was used in this study, application semi-supine combined lithotomy position and the retention of UAS can improve the surgical efficiency and maintain low pressure perfusion in the kidney, which resulted in superior treatment efficacy. Therefore, we highly recommend this technique for LPSs with heavy stone burdens.
