Background Open conversion rates during laparoscopic cholecystectomy vary depending on many factors. Surgeon experience and operative difficulty influence the decision to convert on the grounds of patient safety but occasionally due to technical factors. We aim to evaluate the difficulties leading to conversion, the strategies used to minimise this event and how subspecialisation influenced conversion rates over time. Methods Prospectively collected data from 5738 laparoscopic cholecystectomies performed by a single surgeon over 28 years was analysed. Routine intraoperative cholangiography and common bile duct exploration when indicated are utilised. Patients undergoing conversion, fundus first dissection or subtotal cholecystectomy were identified and the causes and outcomes compared to those in the literature. Results 28 patients underwent conversion to open cholecystectomy (0.49%). Morbidity was relatively high (33%). 16 of the 28 patients (57%) had undergone bile duct exploration. The most common causes of conversion in our series were dense adhesions (9/28, 32%) and impacted bile duct stones (7/28, 25%). 173 patients underwent fundus first cholecystectomy (FFC) (3%) and 6 subtotal cholecystectomy (0.1%). Morbidity was 17.3% for the FFC and no complications were encountered in the subtotal cholecystectomy patients. These salvage techniques have reduced our conversion rate from a potential 3.5% to 0.49%. Conclusion Although open conversion should not be seen as a failure, it carries a high morbidity and should only be performed when other strategies have failed. Subspecialisation and a high emergency case volume together with FFC and subtotal cholecystectomy as salvage strategies can reduce conversion and its morbidity in difficult cholecystectomies.
Objectives: We aim to evaluate our policy of index admission management of gall bladder empyema and the effect of the timing of surgery on the outcomes. Methods: We analyzed a series of 5400 laparoscopic cholecystectomies. Data were collected prospectively over 26 y. Patients were divided into two groups: group 1, intervention within 72 h, and group 2, intervention after 72 h of admission. We had a policy of intention to treat during the index admission, but delays sometimes occurred because of late referral, a need to optimize patients, availability of theater time, or the biliary surgeon being on leave. The groups were then compared with regard to the duration of surgery, the difficulty grading, complications, hospital stay, and conversion rate. Results: A total of 372 patients were included; 160 (43%) operated on within 72 h (group 1) and 212 (57%) after 72 h (group 2). There was no statistically significant difference between the two groups with regard to the operation time, conversion rate, and complications rate. The difference in total hospital stay was, however, statistically significant. Conclusion: Surgical management of empyema should be offered as soon as possible after admission as with any acute cholecystitis. Surgery carried out after 72 h of admission is only associated with longer hospital stay but no statistically significant differences in other outcome parameters. In the presence of specialist expertise, fitness for surgery should be the determining factor of whether or not to offer surgery to these patients, regardless of the interval since their admission.
Aims To assess the incidence of underlying colorectal malignancy in patients admitted as an emergency with a CT diagnosis of acute diverticulitis and determine the need for routine follow up colonoscopy Methods A retrospective study was performed on all patients who had been admitted to our surgical unit with CT diagnosed diverticulitis from September 2016 to September 2018 (n = 125). Results 11 patients (8.8%) required emergency resection with no underlying malignancy found. 76 patients (61%) had a follow up colonoscopy after being discharged. 4 patients were found to have an underlying colorectal malignancy, one of them suspected on CT and another an incidentally detected caecal polyp cancer. Therefore 3/87(3.4%) had an unexpected cancer diagnosis and all those in the diseased segment were within complicated diverticulitis. Conclusion Nowadays, multi-slice CT scanners are so good at giving an accurate assessment of colonic pathology. In our study, 96.6% of the patients with a CT diagnosis of acute diverticulitis had no underlying malignancy in the diseased segment with all the cancers within complicated diverticulitis. With such a low yield of underlying malignancy in uncomplicated diverticulitis, we question the need for routine follow up colonoscopy when there is no CT suspicion of malignancy in these patients
Aim: This study aims to evaluate the incidence, indications, management, and long term follow up of cholecystectomy in patients with no gallstones, other than acalculous acute cholecystitis. Methods: Prospectively collected data of 5675 patients undergoing laparoscopic cholecystectomy (LC) over 28 years was extracted and analyzed. Patients with biliary symptoms, no stones on ultrasound scans and abnormal hepatobiliary iminodiacetic acid scans, and those with confirmed gallbladder polyps (GBP) were included. Results: Two percent of cholecystectomies were performed in patients with acalculous pathology [1.3% functional gallbladder disorder (FGBD) and 0.7% GBP]. The 114 patients were younger, had lower American Society of Anesthesiologists classification, and had fewer previous biliary admissions than those with gallstones (5560). The clinical presentations of FGBD were chronic biliary symptoms (93.1%) and acute biliary pain (6.9%). GBP patients presented with chronic biliary symptoms. LC in 98.6% FGBD and 92.8% GBP were significantly easier than those for gall stones (P < 0.0001). They were significantly (P < 0.0001 FGBD and P < 0.001 GBP) less likely to have adhesions to the gallbladder. This ease was reflected in shorter operation times and lower utilization of abdominal drains. Polyp numbers ranged from 1 to 30 and sizes from 1 mm to 11 mm. No malignant polyps were encountered. In 95.8% FGBD and 95% GBP, patients had a good symptomatic response to LC. Conclusions: FGBD and GBP are uncommon in patients undergoing LC. FGBD should be considered during evaluation of right upper quadrant pain with no gall stones. Laparoscopic cholecystectomy may be considered as it achieves long term symptomatic relief in most patients with FGBD and GBP.
