Risk factors of conversion in laparoscopic cholecystectomies for lithiasic acute cholecystitis. Results of a monocentric study and review of the literature.

INTRODUCTION: Nowadays, laparoscopic cholecystectomy has become the gold standard in the management of lithiasic acute cholecystitis. However, the rate of conversion to laparotomy remains considerable, greater than that of uncomplicated lithiasis. Some factors, related to the patient, the disease or the surgeon, are associated with a high risk of conversion. AIM: To identify the factors associated with a significant risk of conversion in laparoscopic cholecystectomy for acute cholecystitis. METHODS: Between January 2011 and December 2015, all patients operated on for acute cholecystitis at the Department of General and Digestive Surgery of Farhat Hached University Hospital of Sousse - Tunisia were divided into two groups: A for the laparoscopic approach and B for conversion. We compared the two groups. RESULTS: The conversion rate was 21.9% (43 patients). At the end of this work, we found that the conversion rate was significantly increased for males (p = 0.044), ulcerative disease (p = 0.004), smokers (p = 0.007), ASA score = II (p = 0.005), abdominal guarding (p = 0.001), fever (p = 0.001), perivesicular effusion on ultrasound (p = 0.041), ultrasound Murphy's sign (p = 0.023), delayed cholecystectomy (p = 0.038), perivascular adhesions (p <10-3) and gangrenous cholecystitis (p = 0.009). CONCLUSION: The conversion is sometimes badly perceived by the surgeon. However, it should in no way be considered a failure, but rather a change of strategy to ensure patient safety. Conversion should not be delayed, especially as risk factors have been identified.

Laparoscopy for perforated duodenal ulcer: A morbidity score based on a cohort study of 384 patients.

BACKGROUND: The Laparoscopic treatment of perforated ulcer is accompanied by a lesser morbidity and mortality compared with treatment by laparotomy. However, the morbidity of the laparoscopic approach is not nil (4%). It is influenced by pre and intraoperative factors. The aim of our work is to establish a morbidity score in patients undergoing laparoscopic surgery for acute peritonitis with perforated duodenal ulcer. METHODS: This is a retrospective study conducted in a General Surgery Department. We included 384 cases of perforated duodenal ulcer operated laparoscopically over a fourteen-year period ranging from January 2000 to December 2014. We conducted a multivariate logistical regression analysis by step-by-step-descending method. From these independent factors we established a score using the ROC curves. The threshold with the best sensitivity and specificity for predicting morbidity was investigated. In all statistical tests, the significance level was set at 0.05. RESULTS: The overall morbidity rate of our patients was 3.38% (13 patients). Multivariate analysis has identified five independent morbidity risk factors: temperature higher than 37.6° C, renal failure, age> 45 years, a number of stitches of two or higher and operating time to 75 minutes or longer. Our morbidity score took into account these 5 factors by integrating the intrinsic value of each factor. The threshold of the score having the best torque sensitivity specificity to predict morbidity was 10. CONCLUSION: A morbidity score for perforated duodenal ulcer surgery performed by laparoscopy may be useful to organize the post-operativecare of these patients usually young and active. A lower score than the threshold predictive of morbidity could allow a rapid rehabilitation of these patients and a one day hospitalization management.

Observance of the practice of digital rectal examination. Survey of general practitioners in East-central Tunisia.

INTRODUCTION: Digital rectal examination (DRE) is a simple gesture, used for diagnosis of several diseases. However, some general practitioners (GPs) are practicing it less and less often. AIM: To estimate the rate of unrealized DRE and to analyze the factors preventing threir achievement. METHODS: This is a prospective observational study conducted among 105 GPs practicing in Sousse. We used a pre-established pre-tested and self-administered questionnaire. RESULTS: We identified 551 DRE that were indicated but unrealized. There was a significant influence between the non-realization of DRE on the one hand, and on the other hand: the lack of experience; the closeness of the specialist; the lack of training and the lack of conviction of the importance of this examination. Embarrassment during the realization of the DRE was felt in 69.3% of cases. Factors associated with this embarrassment were: female practitioner; the young age of the practitioner; the rural practice and the nature of internship placements. CONCLUSION: Although it is a simple and inexpensive gesture, the DRE remains neglected by many physicians. Several factors appear to influence the achievement of the DRE. Ongoing continuing medical education seems necessary, especially as we found a lack of belief in the importance of this examination.

Partial spontaneous anal expulsion of the right colon lipoma: An exceptional diagnostic circumstance.

INTRODUCTION: Lipomas are most common benign tumors of the colon. They are asymptomatic and fortuitously discovered on a morphological examination. Rarely, they cause complications such as acute intussusception. In this article, we reported an exceptional discovery mode of right colon lipoma. CASE PRESENTATION: A 54-year-old woman has consulted for acute abdominal pain relieved by the anus emission of a fat ball that she brought back with her. Abdominal computed tomography scan showed the remaining part of a lipoma developed in her right colon. Laparoscopic right colonic resection was performed. DISCUSSION: Colic lipomas are usually asymptomatic and surgical indication in these cases is debated, but it is indicated whenever complications occur such as acute intestinal intussusception. In this case, discovery mode was not considered as a complication because lipoma evacuation could have been complete. Radiological explorations and colonoscopy could evaluate the lesional state. When surgery is decided, intersecting therapeutic strategy of a short colonic resection guided by a colonization during colonoscopy should be considered. CONCLUSION: The spontaneous expulsion of a colonic lipoma is very rare. Our observation showed that this expulsion may be partial. +The changes that the lipoma undergoes can evoke a malignant cause. a supplement to take care of this eventuality is necessary.

Early versus delayed laparoscopic cholecystectomy for lithiasic acute cholecystitis during emergency admissions. Results of a monocentric experience and review of the literature.

BACKGROUND: It is established that the standard treatment for lithiasic acute cholecystitis is the laparoscopic cholecystectomie. However, the question of the timing of cholecystectomy remains controversial. AIM: To compare early laparoscopic cholecystectomies (within 72 hours of symptom onset) and delayed laparoscopic cholecystectomies (beyond 72 hours) for lithiasic acute cholecystitis in terms of intra-operative difficulties and post-operative complications. METHODS: The patients operated on for acute cholecystitis, between January 2007 and December 2012, were included in a retrospective study. They were divided into two groups based on whether surgery was performed before (group A) or after (group B) 72 hours after the onset of symptoms. We conducted a comparison between the two groups. RESULTS: The two groups were comparable in terms of background, clinico-biological presentation, and radiological findings. The average time of surgery was 111.6 hours after symptom onset.  Duration of surgery was significantly longer for group B (97 minutes versus 82.17 minutes, p = 0.003). There was more conversion in group B than in group A, without significant difference (20% versus 11.6%, p = 0.14). There were no deaths in our series. Specific post-operative complications were comparable between the two groups (wound infection: 3 (B) versus 1 (A), biliary fistula: 8 (B) versus 0 (A), p = Non significant). The post-operative hospital stay was significantly longer in group B (3.34 days versus 1.84, p <10-3). CONCLUSION: In case of early laparoscopic cholecystectomy, the conversion rate and post-operative morbidity are comparable to the delayed treatment of acute cholecystitis. But the early surgery can reduce the cost of care, the duration of surgery and the hospital stay. Key-words : Lithiasic acute cholecystitis ; Laparoscopic cholecystectomy.
