Isolated papillary muscle rupture complicating acute pancreatitis

Papillary muscle rupture in the absence of coronary stenoses is a rare event. An isolated infarction of the papillary muscle is involved in most cases, but the pathogenesis is still debated. We describe an anterolateral papillary muscle rupture complicating acute pancreatitis in a patient without significant coronary stenoses and with evidence of coronary spasm. This suggests that an increased susceptibility to coronary spasm and thrombosis, triggered by an acute systemic inflammatory response, may represent a mechanism of selective papillary muscle infarction.     

Laparoscopic common bile duct exploration

OBJECTIVE: To describe the technique of laparoscopic common bile duct exploration (LCBDE) with high clearance rates, low morbidity, and mortality rates. SUMMARY BACKGROUND DATA: LCBDE is well accepted by patients because treatment is obtained during the same anesthesia. If one stage therapy for gallstones and common bile duct stones provides success rates equivalent to those of the sequential approach, with lower costs, this should be considered the standard of care. METHODS: From September 1991 to March 2007, 5201 laparoscopic cholecystectomies were performed at S?o José Avaí Hospital. LCBDE was carried out in 481 patients (9.25%). RESULTS: Of 481 LCBDE, 225 (46.78%) were managed using a transcystic approach and 183 (38.05%) with choledochotomy (114 with transcystic choledochotomy and 69 with longitudinal opening of the common bile duct). Successful laparoscopic stone clearance was achieved in 468 (97.3%). An elective postsurgical endoscopic sphincterotomy were done on the 13 (2.70%) patients not cleared laparoscopically. Seven patients had unexpected retained stones. CONCLUSIONS: LCBDE during laparoscopic cholecystectomy solves 2 problems during the same anesthesia with high success rates and may be employed successfully.     

Anastomotic leaks: technique and timing of detection

Background

Despite the proven benefits of laparoscopic colorectal surgery, the rate of anastomotic leaks has not changed. This study looks at the time of presentation of anastomotic leaks between laparoscopic and open colectomies.

Methods

Retrospective chart review was performed between July 2008 and 2012. Two groups were created, laparoscopic and open. The time of presentation of significant leaks requiring reoperation were compared between the groups by index colectomies. Statistical analysis is presented as paired t test and chi-square test (P < .05).

Results

From 1,424 segmental colectomies, the anastomotic leak rate between the two groups was not statically significant (P = .69). No difference in the time of leak detection was evident (P = .67). Mortality rate was equal between the groups. The overall complication rate of the entire cohort was statically significant (P ≤ .001).

Conclusion

The timing of anastomotic leak detection does not differ between laparoscopy and open colorectal resections.     

A novel approach for the treatment of pelvic abscess: transrectal endoscopic drainage facilitated by transanal endoscopic microsurgery access

Background

Postoperative pelvic abscesses in patients submitted to colorectal surgery are challenging. The surgical approach may be too risky, and image-guided drainage often is difficult due to the complex anatomy of the pelvis. This article describes novel access for drainage of a pelvic collection using a minimally invasive natural orifice approach.

Methods

A 37?year-old man presented with sepsis due to a pelvic abscess during the second postoperative week after a Hartmann procedure due to perforated rectal cancer. Percutaneous drainage was determined by computed tomography to be unsuccessful, and another operation was considered to be hazardous. Because the pelvic fluid was very close to the rectal stump, transrectal drainage was planned. The rectal stump was opened using transanal endoscopic microsurgery (TEM) instruments. The endoscope was advanced through the TEM working channel and the rectal stump opening, accessing the abdominal cavity and pelvic collection.

Results

The pelvic collection was endoscopically drained and the local cavity washed with saline through the scope channel. A Foley catheter was placed in the rectal stump. The patient’s recovery after the procedure was successful, without the need for further intervention.

Conclusions

Transrectal endoscopic drainage may be an option for selected cases of pelvic fluid collection in patients submitted to Hartmann’s procedure. The technique allows not only fluid drainage but also visualization of the local cavity, cleavage of multiloculated abscesses, and saline irrigation if necessary. The use of TEM instrumentation allows safe access to the peritoneal cavity.     

Clinical patterns of spontaneous recovery of paralyzed triceps brachii associated with C5 to C7 injuries of the brachial plexus

Some patients who sustain C5 to C7 nerve root injuries may demonstrate a natural recovery of elbow extension via the lower trunk; however the surgical effect of the reinnervation of the triceps brachii in such cases is still unknown. This study aims to determine the incidence of spontaneous recovery of the tricipital function and to identify the clinical and/or radiological predictors of poor spontaneous functional rehabilitation of elbow extension resulting from injuries of the upper roots of the brachial plexus. We conducted a review of the charts of 24 subjects sustaining an upper trunk syndrome with complete elbow extension palsy and who did not undergone any intervention for reinnervation of the triceps brachii in the primary brachial plexus surgery. Two years posttrauma, the muscle was scored as M0 in 12 patients (50%), M1 in 3 (12.5%), M2 in 1 (4.1%), M3 in 4 (16.6%), and M4 in 4 subjects (16.6%). The number of avulsed roots and the preoperative power of the latissimus dorsi did not demonstrate any significance in predicting the outcome of spontaneous elbow extension recovery; whereas the preoperative paralysis of the muscles for wrist extension was determined to be reliable predictive parameter for poor natural recovery of tricipital function.
