Laparoscopic subtotal cholecystectomy; change in practice over a 10-year period.

BACKGROUND: Laparoscopic subtotal cholecystectomy is a recognised safe, alternative strategy when a critical view of safety cannot be obtained. This study audits the change in practice at a District General Hospital following the adoption of subtotal cholecystectomy in 2013. METHODS: Retrospective case series included consecutive cholecystectomies over a ten-year period in a single institution. Cases were divided into subgroups based on operation date. Primary outcome was the proportion of patients undergoing laparoscopic total cholecystectomy, laparoscopic subtotal and laparoscopic converted to open cholecystectomy. Secondary outcomes included incidence of bile leak, complication rate, return to theatre, and length of stay. RESULTS: There were 4217 cases: 1381 in Group A (pre-adoption of subtotal cholecystectomy 2009-2012), and 2836 in Group B (post-adoption of subtotal cholecystectomy 2013-2019). The rate of laparoscopic total cholecystectomy was higher in Group A than Group B (95.4% vs. 92.8%, p < 0.001). In the subtotal group (n = 114, 14 (12.3%) patients had bile leak, 6 (5.3%) underwent re-laparoscopy, and median length of stay was 2 days. CONCLUSION: Laparoscopic subtotal cholecystectomy appears to be an acceptable alternative technique at this centre, reducing the rate of open conversion and length of stay, with a low reintervention rate for bile leak.

Conventional Surgical Management of Bile Duct Stones: A Service Model and Outcomes of 1318 Laparoscopic Explorations.

OBJECTIVE: The primary aim of this study was to describe the service model of one-session management, with a limited role for preoperative endoscopic clearance. The secondary aim was to review the outcomes and long term follow up in comparison to available studies on LCBDE. BACKGROUND: The laparoscopic era brought about a decline in the conventional surgical management of common bile duct stones. Preoperative endoscopic removal became the primary method of managing choledocholithiasis. Although LCBDE deals with gallstones and ductal stones in onw session, the limited availability of such an advanced procedure perpetuated the reliance on the endoscopic approach. METHODS: Prospective data was entered into a single surgeon's database containing 5739 laparoscopic cholecystectomy over 28 years and analyzed. RESULTS: One thousand eighteen consecutive LCBDE were included (23% of the series). Intraoperative cholangiography was performed in 1292 (98.0%). The median age was 60 years, male to female ratio 1:2 and 75% were emergency admissions. Most patients (43.4%) presented with jaundice. 66% had transcystic explorations and one third through a choledochotomy with 2.1% retained stones, 1.2% conversion, 18.7% morbidity, and 0.2% mortality. Postoperative ERCPs were needed in 3.1%. Recurrent stones occurred in 3%. CONCLUSIONS: One stage LCBDE is a safe and cost-effective treatment where the expertise and equipment are available. Endoscopic treatment has a role for specific indications but remains the first-line treatment in most units. This study demonstrates that establishing specialist services through training and logistic support can optimize the outcomes of managing common bile duct stones.

Dropped gallstones causing abdominal wall abscess and pleural empyema: a case series.

INTRODUCTION: Dropped gallstones are gallstones lost in the abdominal cavity during cholecystectomy. They are a rare occurrence and often cause minimal long-term issues. However, it is recognised that dropped stones can cause intra- or extra-abdominal sepsis. We present three cases below which highlight this. CASES: All three cases describe patients presenting for laparoscopic cholecystectomy, Cases 1 and 2 post-gallstone pancreatitis and Case 3 for gallbladder stones. Cases 1 and 3 presented nine months and five years post-operatively, respectively, with flank abscess. Both received CT scans, with incision and drainage performed to remove gallstone. Case 2 presented six weeks post-operatively with cough and breathlessness. CT scan showed pleural effusion with communication to subphrenic collection. Pus and gallstone fragments were drained. CONCLUSION: The above cases highlight that despite the majority of patients remaining asymptomatic, dropped gallstones should be considered amongst the differential in patients presenting with intra- or extra-abdominal abscess post-cholecystectomy, with timely intervention key to management.

Bad expression predicts outcome in patients treated with tamoxifen.

AIMS: Activation of the PI3K/Akt signal transduction pathway has been linked to endocrine resistance in tamoxifen treated breast cancer patients. Activation of the PI3K/Akt pathway causes phosphorylation of Bad leading to modulation of cellular apoptosis. The present study was carried out to test the hypothesis that disruption of apoptosis in breast cancer, via Akt activation, is linked with hormone resistance. METHODS: Immunohistochemistry (IHC) was performed on 402 oestrogen receptor (ER) positive breast cancers using antibodies against Bad, pBad (ser 112), Bcl-2, Bcl-xl and Bax. RESULTS: Bad, pBad (ser 112), Bcl-2 and Bax expression was observed in the cellular cytoplasmic compartment only. Patients, whose tumours had high levels of Bad expression, had a significantly improved disease-free survival when compared to patients whose tumours had low levels of Bad expression (P = 0.049). Activation of the PI3K/Akt pathway by either heregulin or oestrogen had no effect on expression of Bad, Bcl-2, Bax or Bcl-xl. However, heregulin increased pBad (ser 112) expression. DISCUSSION: Data presented here shows that Bad expression is associated with relapse in tamoxifen-treated breast cancer patients, supporting our hypothesis that the apoptosis pathway is involved in tamoxifen resistance.
